When a cover letter matters
A cover letter is optional at some companies and expected at others. When in doubt, write one. It's a low-cost signal that you're actually interested in this specific role, not mass-applying. Skip it only if the posting explicitly says not to include one.
The three-paragraph formula
Every strong cover letter does three things in three paragraphs. Each paragraph has a job to do.
- Paragraph 1 — The hook. Why this role, why this company, why now. One or two sentences that show you read the posting and have a specific reason to apply.
- Paragraph 2 — The proof. One or two concrete achievements that directly answer what the role needs. This is where you make the case that you can do the job.
- Paragraph 3 — The close. A short, confident closing that thanks them and states your interest in talking. Do not say "I look forward to hearing from you" — say something specific.
Opening lines that work
- "I've spent the last four years building backend systems at [Company], and the [Role] at [Your Company] is the first posting in a while that made me stop and read every line."
- "When I saw that [Company] is hiring a [Role], I recognized the exact problem you're solving — I worked on a similar challenge at [Previous Company]."
- "I've been following [Company] since [specific event/product/news], and the work on [specific thing] is why I'm applying."
Avoid: "I am writing to express my interest in the [Role] position." It's what everyone writes.
Example body paragraph
At [Previous Company], I led the redesign of the public API gateway used by 200+ enterprise clients. By restructuring the request handling and moving to a caching layer, we cut median response times by 38%. That work is close to what the posting describes for [Your Company], and I'd bring the same approach: understand the constraint first, then design around it.
Closing paragraph
Short and confident. "I'd like to walk through how this maps to your roadmap. I'm free next week and can be reached at [email] or [phone]." Don't hedge. Don't apologize. Don't say you're "just" anything.
What to avoid
- Repeating your resume line by line.
- Starting with "I am writing to..."
- Generic praise for the company — "I love your culture."
- Long paragraphs over four sentences.
- Apologizing for a gap or for lack of experience.
- Copy-pasting the same cover letter to every role.
Frequently Asked Questions
How long should a cover letter be?
Three short paragraphs, roughly 200–300 words. Anything longer gets skimmed and skipped. Anything shorter feels like you didn't try.
Should I address a specific person?
Yes, if you can find the hiring manager's name. Otherwise, "Hiring Team" or "Dear Hiring Manager" is fine.
Do I need a cover letter if the posting doesn't ask for one?
Not always, but a well-written cover letter rarely hurts and often helps. It's a low-cost way to stand out.
Can I use the same cover letter template for every job?
You can use the same structure, but each cover letter should be tailored — different hook, different proof, different tone.
